Application filed July 24, 1922. serial No. 577,0?35.

To all whom it may concern:

Be it known that we, MAXIMILIAN E. Bones and WALTER W. BUHSE, citizensof the United States, residing at Minneapolis, in the county of Hennepinand State of Minnesota, have inventedcertain new and useful Improvementsin Ice-Cream-Cone- Goatin Devices; and we do hereby declare the folowing to be a full, clear, and exact description of the invention,such.as will enable others skilled in the art to which it "ap' ertainsto make and use the same.

' ur present invention rovides an extremely simple and highly eEcientdevice for a plying fluid confection coatings to shellli e pastry andhas been especial designed for use in applying chocolate coatings to theinteriors of ice-cream cones.

The chocolate which is to form the coating and which is usually mixedwith'a small ount of cocoa butter, is kept in proper fluid condition byartificial heat. In the preferred form of our improved-device or aparatus, the chocolate is placed in a vat, t e vat is partly immersed inwater contained in a water tank, and the water in said tank is kept atthe proper degree of temperature by a small electric heater or suitablesource of heat.

Immersed within the liquid chocolate or coating material and tionconnected to the pump, and certain other important novel features, allof which will be hereinafter described and defined in In theaccompanying drawings, which lustrate the invention, like charactersndicate like parts throu hout the several views.

Referring to the rawings:

Fig. 1 is a vertical lon 'tudinal section taken centrally -through t ecomfilete device some parts beshown in in F1 25s a vertical section onthe hue 2-2 of Fig. 1;

Fig. 3 is a fragmentary on a larger so than in showin the pum and acharge 'aucet; an

Fig. a is a detail in horizontal section on the line 44 of Fig1 3.

{The tank in whic. the hot water is maintained is preferably arectangular cast metal structure. 5 havin short supportinglegs 6 andprovided on 1ts bottom with an electr1c heater Tconnecicd in a supplycircuit 8.

vertical section the othep views, cooperating discontained within thevat is a pump, a fountain of novel construe- The vat 9, for containi vthe chocolate or coating material y, fits' within the tank 5 and isprovided with an outstanding flange 10 that rests on the up or edge ofthe latter. The lower portion 0 the vat 9 is transversely contracted anda portion thereof is ra sed above a pump-receding space 9 or said vat.At one end, the tank 5 is shown as provided with a funnel-like fillingneck 11 through which water may be poured to maintain the level of thewater in the tank so that the vat will be properly immersed therein. Theelectric heater 7 comprises a drawer-like metal casing with outstandingfiangles working slidably in guide clips 12 on t e bottom of the watertank so that said electric heater can be readily removed from andapplied to the tank.

The pump for forcing the liquid coating out of the vat comprises a shortcylinder 13 and a dasher-acting piston 14. The cylinder 13 is secured onthe bottom of the vet in the depressed s ace 9 and has ustandingcircumferentia iv spaced guide u 15 that normally hold the piston heaaligned with the interior of the cylinder.

The piston head 14 has an upwardly project-- ing stem 16, which, asshown, is threaded at its upper end and adjustably screwed into the stem17 of an operating knob 18. As shown,

the stem 17 is square in cross-section and works through a square holein a to plate 19 fixed on the top of the vat. l the threaded portion ofthe stem 16 is a sto collar 20. The numeral 21 indicates a helica coiledspring, the ends of which are anchored to the top plate 19 and thecontracted central portion of which surrounds the stem 16 and pressesthe stop collar 20 upward a ainst the plate 19- and thus normally hol sthe piston head 14 above the upper edge of the cylinder 13, but notbeyond t e as shown in Fig. 1. In the said osition 0.

parts shown in Fig. 1, the liqui chocolate or coating will overflow intoand fill the, cylinder 13. Near its bottom, the cylinder 13 is providedwith two ports 22 and 23 that connect, respectively, to a iountain tube24 and to a fauc'et tube 25. 'e extended portion of the fountain tuhe 24is turned vertically outward and is threaded and onto this threaded endis screwed a tuhul'ar discharge nozzle 26'. This nozzle 26 is formedwith an outstanding, downwardly oblique annular deflecting flange 27.Thenumeral 28 indicates a concave convex substantially conguide lugs 15%ical deflecting cap shown as secured on the upper end of the rod 29 thatextends axially downward in the nozzle 26 and has a laterally bent lowerend directly secured to said nozzle 26.

Adjustably secured for vertical sliding adjustments on the nozzle 26, bymeans of a set screw 30, is a collar having outwardly and upwardlyextended circumferentially spaced arms 31 that support an upwardlyflaring annular cone-centering ring 32, which latter islocatedconcentric to but which is much larger than the deflecting flange 27.

The faucet tube extends vertically upward through the fixed plate 19 andis clamped in position by nuts 33 that work with threaded engagement onsaid stem and ress against the bottom and top of said fixed plate 19.The upper end of the faucet tube 25 is connected to an outwardlyextended faucet nozzle 34. At the connection between the faucet tube 25and nozzle 34, said tube is provided with a two-way valve 35 shown asprovided with an operating handle 36. This valve 35 has anaxial bore 37and lateral delivery port 38.

When the valve 35 is in the position shown in Fig: 3, the interior ofthepump cylinder 13 will be cut off from the faucet nozzle 34, but theaxial passage of said tube 25 will then be in communication with areturn duct 38 formed in said tube. When the valve 35 is turned onehundred and eighty degrees from the position shown in F i 3, the returnduct 38 will be closed and t e interior of the cylinder will beconnected to the faucet nozzle 34.

The numeral 39 indicates a, removable cover plate which will be appliedto the top of the vat and will serve to close the same when the deviceis out of use. In Fig. 2, an ice-cream cone 40 is indicated by dottedlines.

When the device is to be used, the cover plate 39 will beremoved or slidinto'position to expose the fountain head, but when the device is to beused to internally coat ice-cream cones, the valve 35 should be set inits .closed position, shown in Fig. 3, and the cone inverted willbeplaced over the deflecting ca 28 and the deflectin flange 27 and itslower edge will be placed within the conical centering ring 32. Thisring 32 will serve to properly center or align the cone axiallywith theelements of the fountain head. The centering ring 32 should bevertically adjusted so that there will be the proper slight spacebetween the cone and the edges of the cap 28 and flange 27. Then, whenthe plunger-acting piston 14 is substantially forced downward bypressing downward on or striking the operatmg knob 18, there will be arush of the liquid coatin the fountain tu e 24 and against the defurtherunderstood that material upward through flecti cap 28. The coatingmaterial dashef against the under surface of the cap 28 will bedeflected outward in all directions against the interior of the cone andwill be violently caused to rush downward, partly by momentum and partlyby gravity and, as it runs over the deflecting flange 27, will be againdirected against the inner surface of the cone. The surplus coatingmaterial will continue to run down over the inner surface of the cone,coating the same from the points'of first application to the lower edgethereof. Of course, the surplus coating material dripping from the conewill run back into the vat. It will thus be seen that the cone will bechocolate coated, not to the complete apex thereof, but from a pointquite distant from its apex to the rim of the cone When the valve 36is'turned one hundred and eighty degrees from the position shown in Fig.3 and the pistonof the pump is forced downward as before described,there will be a discharge of the coating material through the faucetnozzle 34, so that a deposit of the li uid chocolate or the like may bedelivere onto the ice-cream deposited in the cone or onto a scoop ofice-cream contained in a dish or other container .for forming achocolate sundae.

0f course, each time there is a discharge of the chocolate through thefaucet for the purpose just stated, there will also be a dischargethrough the fountain, but this' keeps the fountain conduits open and thedischarge would sim 1y drop back into the vat. ,The amount 0 thedischarge may be varied by the force or extent of the depression of thepump piston. It will be I when the valve 35 is set in a position ninetydegrees firom the position shown in Fig. 3, both the, faucet nozzle 34and the return duct"38;will be closed and sometimes this will be founddesirable.

In actual practice, this device has been found veryefiicient for thepurpose had in new. Vertical adjustments of the cone cen- *termg ring 32make it possible to set the cone so the coatin of more or less of thelnterior thereof Will be chocolate.
